Battery life is an important thing, for me, in using my iPhone and my Apple Watch. I have been fortunate that with my decision of smartphones (all iPhones) and the non-need to be notified every second of my life has worked out that usually I don’t have to charge my iPhone more than once every 20 hours with normal use.

Normal use for me is: check email manually (I check it a few times a day); Tapatalk and Facebook (a few times a day); surfing web pages; updating my web site; and checking my fitness/health.

What is out of normal for me is: watching Videos (twice a week for an hour and a half each time); playing music; using directions with the Map app; using the Workout app (walking daily); and video game playing (RuneQuest for instance).

So through that I have been able to extend this to my Apple Watch. Right now I can get two days worth (12 hours a day) out of a single charge. How I accomplished this is to first tell all Apple Watch compatible apps: Not install by default, turn off “Mirror iPhone Alerts from” for the apps I don’t want to notify me on the Watch, and turn off apps I don’t need to appear in my Glances on the Watch. Pretty simple but it works. Any day can be a combination of normal and out of normal.

A normal two day pattern for me is to (using Apple Watch 1.0)

Get up and put my Watch on (take it off the charger) after I get dressed at 7am (100% battery power left)

At 8pm I put my Watch away as I won’t be needing it anymore by putting it into Power Reserve Mode (56% battery power left)

At 7am the next day reboot it at 7am (54% battery power left)

At 8pm put it on the aluminum charging stand (The watch turned on the Power Reserve Mode automatically at less than 3% battery power left. I skipped the 10% BRM notification. I don’t know at what percent when it turned BRM on but it did.)

I tested this again another set of two days (using Apple Watch 1.0.1):

Get up and put my Watch on (take it off the charger) after I get dressed at 7am (100% battery power left)

At 10pm I put my Watch away as I won’t be needing it anymore by putting it into Power Reserve Mode (57% battery power left)
